Why Did Australia and New Zealand Switch to Screwcaps? The Real Screwcap Wine History
The screwcap wine history is shorter than you’d think, and a lot crosser. It barely runs thirty years, and for a fair chunk of it, people were writing furious letters. A screwcap is an aluminium cap rolled — not screwed — onto a specially shaped bottle neck, sealed with a plastic or tin liner. It does one job: keep the wine as the winemaker left it, without cork’s occasional habit of quietly ruining a bottle in the dark. By the end of this, you’ll know why the switch happened, what it means for the bottle in your hand, and when (if ever) to hesitate over one.
What actually happened
Screwcaps aren’t new. According to industry accounts, a French company developed the idea in 1959, borrowing packaging tricks from spirits bottling. It went nowhere in wine circles at the time; nobody trusted it, and cork’s faults weren’t yet common knowledge. An Australian packaging firm bought the rights around 1970 and brought it to market under a new name. Trials through the 1970s reportedly found screwcaps sealed wine perfectly well, provided the liner and the bottle lip were right — but the push fizzled again, mostly for lack of consumer appetite.
The real turn came around 2000. A group of Clare Valley Riesling producers, sick of writing off cases to failed corks, switched over. New Zealand watched from across what winemakers there call “the ditch,” and in 2001 a group of wineries formed the New Zealand Screwcap Wine Seal Initiative, with reports putting the founding membership at around thirty. One winery declared its entire production cork-free that year — a properly bold call at the time. A well-known winemaker later admitted he’d had letters from expatriate wine drinkers accusing the industry of ruining its own reputation. It wasn’t a quiet changeover.
An Australian research body ran a large study around the same time, and the results mattered: screwcaps reportedly held free SO2 better and avoided cork taint almost entirely. Trade coverage from the period suggests New Zealand’s screwcap use climbed from a small single-digit share in 2001 to roughly 70% within a few years — a genuinely fast flip for an entire industry. If you want the wider picture of how these two countries make wine now, our Australia and New Zealand: a merchant’s guide to the wines of the antipodes covers more than closures. All those cross letters bought you something concrete, though: the screwcapped bottle you pick up tonight pours exactly as its maker intended — which is the whole argument, settled in your favour.
Does a screwcap mean the wine is cheap?
No — not in Australia, New Zealand, or here in the UK. Trade reporting on closures suggests screwcap acceptance is well established across all price points in these markets, including plenty of wine you’d happily bring to someone’s table without apologising for the cap. In the US and China, the old association with cheap bottling still lingers, though it’s fading.
I sold wine across the counter for years before I stopped flinching when a customer picked up a £30 Central Otago Pinot Noir and asked, half-joking, “no cork though?” It’s an honest question. But the reason a top New Zealand Pinot or a serious Clare Valley Riesling sits under screwcap isn’t cost-cutting — it’s that the winemaker trusts it more than cork for that particular wine. If you want to see this argument play out region by region, Clare vs Eden Valley Riesling: Australia’s dry white secret is worth a look — both valleys back screwcap hard for their aromatic whites.
Even in England, a number of producers have leaned the same way, bottling aromatic whites under screwcap rather than cork for much the same practical reasons that pushed Australia and New Zealand to switch. It’s not a colonial quirk — it’s a decision made bottle by bottle, grape by grape. If you’re picking a bottle tonight, use that as your steer: for aromatic whites especially — a dry Clare-style Riesling, say, or a crisp New Zealand white — read the cap as a mark of intent, not economy. And when the occasion stretches to that £30 Central Otago Pinot Noir, the cap is the least of the reasons it earns its price.
Can wine under screwcap actually age?
Yes — for most styles bought to drink over the next few years, screwcap is entirely reliable, and for some wines it’s arguably the steadier bet. The genuine debate among winemakers is about very long-term cellaring of serious reds, where cork’s slow oxygen exchange has centuries of track record and screwcap has decades. Both close the gap more than people assume.
The liner does the real work here. Tin liners are close to airtight; Saran (a plastic, similar to cling film) allows a little oxygen through, which is closer to how a good cork behaves over time. Winemakers choose between them depending on the wine and how long they expect it to sit in someone’s rack. It’s a genuinely more legalistic, printed-on-the-label kind of world in some regions — if you enjoy that side of wine, How does Spain’s wine ageing law actually work? is a nice companion read, since Spain does its ageing rules by decree rather than by closure choice.
One quiet advantage: screwcaps barely absorb flavour from the wine (what’s called “scalping”), unlike some synthetic corks. Whatever aromatic lift the winemaker built in tends to still be there when you pour it. For anything you’re buying to drink inside the next few years — which, honestly, is most of what any of us buy — that makes the screwcapped bottle the confident choice, not the compromise.
What’s that whiff on first pour — is that the screwcap’s fault?
Occasionally, yes, sort of. A small number of screwcap wines — usually ones sealed with tin liners that let in almost no oxygen — can show a faint reductive smell on opening, something like a struck match or, if it’s more pronounced, boiled egg. It’s not a fault in the cork-taint sense; it’s an oxygen-starvation thing, and it usually blows off in the glass within a few minutes.
Winemakers who bottle under screwcap generally adjust their sulphur levels downward at bottling to head this off, precisely because they know the liner won’t let much air in to compensate. If a wine still smells stubbornly off after a proper swirl and a few minutes, that’s a different conversation — and one worth reading up on properly in Wine faults beyond cork taint: oxidised, reduced and other off bottles, which goes into the reduction question in more depth than I can here.
Cork vs screwcap: what changes in the glass
| Cork | Screwcap | |
|---|---|---|
| Taint risk | Small but real (TCA) | Near zero — no cork in contact with wine |
| Oxygen ingress | Slow, variable bottle to bottle | Controlled by liner choice (tin vs Saran) |
| Best suited to | Long-cellared reds, traditional markets | Aromatic whites, Rieslings, most everyday reds |
| Opening | Needs a corkscrew | Twists open, no tool needed |
| Global market share | Reportedly around two-thirds of bottles | A meaningful minority, and growing |
Cork still seals most of the world’s wine — that rough two-thirds figure, widely cited by cork-industry sources, hasn’t really shifted. Screwcap took the smaller share and ran hardest with it in exactly the two countries this piece is about.
Questions customers ask us
Does a screwcap wine need to “breathe” before drinking? Some structured reds benefit from a few minutes in the glass or a decant regardless of closure — that’s about the wine’s tannin and age, not the cap. Screwcap doesn’t change this either way.
Why does the UK accept screwcaps more than the US? Trade opinion points to earlier and heavier exposure — UK retailers stocked screwcap New Zealand wine early and in volume, and drinkers got used to it faster than American shoppers did.
Will screwcap ever fully replace cork? Unlikely soon. Cork still holds the majority of the global market, and plenty of producers — especially in Europe’s older regions — see cork as tied to their wine’s identity, not just its seal.
Is the metal itself ever a food safety concern? No — it’s the same aluminium-and-liner setup used across the drinks industry for decades, tested repeatedly by producers before wide adoption.
The merchant’s last word
I used to think screwcap was the “modern” choice and cork the “proper” one — took me a while to unlearn that. Really it’s just two different tools, each suited to different wines and different patience levels. Australia and New Zealand didn’t switch to be clever; they switched because they kept losing good wine to bad corks. Fancy tasting the results for yourself? Browse the Australia cellar and judge the cap on what’s actually in the glass — start with a dry Riesling, where the whole revolution began, and work outward from there.
